As a result of the cause analysis, it was confirmed that the pipe reader process performance was poor. However, what was more problematic than that was the log buffering off option among the LDAP options. When buffering was not used, a block on port 389 occurred on all servers in response to large requests. Here's what I need to do: 1. Increasing the performance of the pipe reader, 2. If the log buffer is not used, measure the limitations of the LDAP server and reflect them in my architecture.
